10 Facts about Earth and its Orbit
Facts about Earth and its Orbit narrate the scientific information about the path of earth to travel around the sun. Earth has to travel 584 million miles or 940 million kilometers to complete an orbit to the sun. It needs 1 sidereal year or 365.256 days. The earth and sun has the average distance of 92.96 million miles or 149.60 million km. Let us check other interesting facts about earth and its orbit below:
Facts about Earth and its Orbit 1: eccentricity
The eccentricity of earth’s orbit is measured at 0.0167. The apparent movement is spotted when the earth has its orbital motion.
Facts about Earth and its Orbit 2: the average orbital speed
The average orbital speed of earth is measured at 67,000 miles per hour or 108 km per hour or 30 km per second.
Facts about Earth and its Orbit 3: the direction
Earth is seen of revolving the sun in counterclockwise direction when you view it from the vantage point at the North Pole.
Facts about Earth and its Orbit 4: Heliocentric
The sun is considered as the center of the solar system in the scientific model of Heliocentrism. The earth and other planets are in the sun’s orbit. Look at facts about earth’s history here.
Facts about Earth and its Orbit 5: geocentrism
Have you ever heard about geocentrism? It was the belief that earth was the center of the system. This model opposes heliocentrism.
Facts about Earth and its Orbit 6: who proposed heliocentrism?
In the third century BC, heliocentric model was proposed by Aristarchus of Samos. The full discussion about this model was elaborated by Nicolaus Copernicus in his De revolutionibus.

Facts about Earth and its Orbit 9: the axial tilt
The trajectory of sun is varied over the years because of the axial tilt of earth.
Facts about Earth and its Orbit 10: the North Pole and sun
The sun looks higher in the sky and shines longer when the North Pole is tilted toward the sun. The surface of earth is warmer due to the solar radiation. The North Pole has cooler weather when it is tilted away from the sun.
